I think part of the reason most ISPs don't support RFC2317 or reverse delegation is that it makes it easy for a bad actor who's in charge of the DNS server being delegated to, to spoof any domain they want. The consequences of this sort of spoofing have now been limited by other systems and protocols anyway, so it's not as big of a deal. ISPs prefer to have direct control of the reverse lookups within their IP blocks so they can ensure the integrity of the information. |
